' That I, LDORMAN, of the city' and. county of lWorcester andCommonwealth of Massa;

ful Improvements i`n yCarriage Wheel Hubs; and I do hereby declare 'thatthe following is 'a full, elear, and exact description ofthe same,reference being had tothe vaccompany-v ing drawings forming la part ofthis specification, in which; p l

Figure l represents. a perspective view ot'fso invention. Fig. 2represents a4 cross central section of the hub shown in Fig. l, line l.Fig. 3 represents a longitudinal central section on line 2 2; andFig.-rcpresents acrosssection on line 3 3, Fig. l. e

'Io enable those skilled in the art' tok which my invention belongs vtomake andl use the same, l will proceed to describe'it. v

l In thedrawings, the part A is made of wood turned a little tapering','to fit closely when driven into the metal shell part 13 the hole inwhich is -'also made a little tapering.- llhe shell part Bis made withtaperingends C C, to combine lightness with strength. Itl is also madewith two ilanges, et a, which prov on each side. It -is also-providedwith aseries ofslots or openin gs, ee, which extend through the shell,the. sidesand ends of vthese 'slots' in this instance.being straight,thereby'leaving the angeler-thrilled ribs f f between the slots oropenings c, as fully shown in the drawings. A groove, g, is turned inthe wood part A, the width being'the same 'as the length of the Aslotsor openings e." lThe wood part A is'also grooved out lengthwise in oneor more places. l1., to receive the pins i on theushell l. The operationof constructing the wheel,

lows: The wood part A is driven into the shell, in which it is kept fromturning by the pins 'i tting the grooves h. The spokes E are then drivenin, seas tooccupy the relative positions shown inL the drawing. It willvisv l.' The combination of the grooved wooden und for the purposes setforth.
